Prof Tomas Vetrik, Professor in the Department of Mathematics and Applied Mathematics at the University of the Free State (UFS), recently delivered his inaugural lecture on the Bloemfontein Campus.

His research area is graph theory, and he mainly focuses on the degree-diameter problem, graph indices, and metric dimension of graphs.

Research focus

According to Prof Vetrik, mathematics was always his favourite subject in school. He also excelled in maths at university and decided to enrol for a course on graph theory while working on his master’s degree. “I liked it, so I also chose topics from graph theory for my PhD thesis,” he says.

In 2014, at the age of 32, he was appointed Associate Professor at the UFS, after postdoctoral research at the University of KwaZulu-Natal and working at the University of Pretoria. An NRF-rated researcher, he has published close to 75 research papers, a third of that as a single author in some of the most well-known journals in his area. Moreover, he was also research supervisor of three PhD and three master’s students.

International collaborations

In the eight years since his appointment at the UFS, Prof Vetrik has made research visits to universities from 14 different countries that have invited him for research collaborations.

“I am often overseas. I like working from different places. It is interesting to me, and it helps me to be productive,” says Prof Vetrik, explaining some of the inspiration behind his mathematical ideas.

In the next two years, he would like to study more general mathematical problems beyond his current research area.

He says he is addicted to his research. “It overshadows all my other interests.”

On the rare occasion when he is not working on his research, Prof Vetrik states that he has to keep himself busy. Unable to relax and do nothing, he likes to do sports of some kind or to travel.

“I am a simple person. I do not even have a TV at home. I use an old-fashioned mobile phone that cannot access the internet,” he says.

Beginning 2013, the Bloemfontein Campus is seeing the opening of two new residences where male and female students will be housed under one roof but in separate units. Each residence will house 250 students.

House ConLaurês and House Outeniqua were opened for their first-years and Residence Committee (RC) on Friday 18 January 2013. The two newly Residence Heads, Mr Frank Makhabane (ConLaurês) and Mrs Leani Wimble (Outeniqua) welcomed the new residents.

The uniqueness of these residences is that they will be the first co-ed residences on campus. These residences are wheel chair friendly with fully equipped disabled rooms available. All signage has also been done in Braille. Each floor of the new residences has two lounges, as well as a fully fitted kitchen.

The Prime of House ConLaurês, Sherilyn Roelofse, says, “We aim to create a living space that is holistic and welcoming and will allow our residence members to be able to excel in a number of things”. Sherilyn says ConLaurês comes from the word “Condo Laurus”, which means dreams of victory. The House’s slogan is “The Symphony of Dreams”. Students came up with the name for the residence.

Tsatsi Mokoena, RC member responsible for RAG at House ConLaurês says RC members have been working hard for the past few months, trying to imagine how to do things without a physical structure. ConLaurês will be a residence with an inspirational living space where each student feels welcome, respected for who they are and at home, so that they will have the confidence to follow their dreams.”

The Prime of Outeniqua, Vusumzi Mesatywa says, “Change is always welcome and that is the mindset that we will be embracing as the new residences. When a student graduates, we need them to graduate not only as academics, but also as humans, holistic beings”.

Marla Stanier, RC First-Year Mentor at Outeniqua, says that new experiences await every student that walks through the doors of the residence. “As excited as we are, this new experience will test us in many ways.However, if we stand together as one, we will succeed.”

Mr Quintin Koetaan, Director of Housing and Residence Affairs, says, “The opening of ConLaurês and Outeniqua is a dream come true, providing accommodation for a new generation of students in the 21st Century”.
